Adam, Bryan and Charlie have some stickers in the ratio of 5 : 2 : 2.
Adam and Bryan have a total of 700 stickers.
- How many stickers does Adam have?
- How many stickers do Adam and Charlie have?
- How many more stickers does Adam have than Bryan?
(a)
Number of stickers that Adam has = 5 u
Number of stickers that Bryan has = 2 u
Number of stickers that Charlie has = 2 u
Number of stickers Adam and Bryan have
= 5 u + 2 u
= 7 u
7 u = 700
1 u = 700 ÷ 7 = 100
Number of stickers that Adam has
= 5 u
= 5 x 100
= 500
(b)
Number of stickers that Adam and Charlie have
= 5 u + 2 u
= 7 u
= 7 x 100
= 700
(c)
Number of more stickers that Adam has than Bryan
= 5 u - 2 u
= 3 u
= 3 x 100
= 300
Answer(s): (a) 500; (b) 700; (c) 300
